This is generally the problem with ISAs.

ARM has had decades in the oven, x86 has had almost half a century, while RISC-V manufacturing and ISA development has been generally available only a couple of years.

The fact is if there isn't a big push by some major vendor - or some nation state, then chances are it'll develop slower than the previously mentioned ISAs.

From design, to testing, to prefab, to packaging, it's all combined just a single step of the journey to improving yield and performance.

ARM is unfortunately the current trajectory, with Qualcomm, Apple and now NVIDIA leading the charge - which doesn't bode well, simply because you won't know what the hell the firmware do.

We could truly use some market disruption in this space and RISC-V, being an open ISA, would be the safest bet for digital sovereignty and user autonomy - but apparently those things are only important on paper.
